Glaucoma Surgery

Glaucoma Surgery is a specialized ophthalmic field focused on reducing intraocular pressure to prevent progressive optic nerve damage and vision loss. As an important topic within a global Surgical Science Conference, this session explores advanced operative strategies, pressure-lowering technologies, and innovations in intraocular pressure surgery that are transforming glaucoma management. With glaucoma remaining a leading cause of irreversible blindness worldwide, timely surgical intervention plays a critical role when medical therapy is insufficient.

Surgical treatment is considered when topical medications and laser therapies fail to adequately control intraocular pressure. Traditional procedures such as trabeculectomy have long been regarded as the gold standard for creating a new drainage pathway to lower pressure. Careful surgical technique and postoperative management are essential to ensure sustained filtration while minimizing complications such as hypotony or infection. Antimetabolite agents are frequently used to improve long-term surgical success.

In recent years, minimally invasive glaucoma surgery (MIGS) has gained significant attention for offering safer, tissue-sparing alternatives in selected patients. These procedures utilize micro-stents and internal drainage devices to enhance aqueous humor outflow with reduced recovery time. MIGS techniques can often be combined with cataract surgery, providing dual therapeutic benefits. Patient selection remains critical, as disease severity and anatomical considerations influence procedural choice.

Complex and advanced glaucoma cases may require tube shunt implantation or revision surgery to maintain adequate pressure control. Surgeons must balance effective intraocular pressure reduction with preservation of visual acuity and ocular integrity. Long-term follow-up and close monitoring are essential to detect complications such as scarring, device failure, or progressive optic nerve damage.

Emerging technologies including micro-shunt systems, sustained-release drug implants, and advanced imaging modalities continue to expand surgical possibilities. Integration of optical coherence tomography and digital pressure monitoring enhances preoperative assessment and postoperative surveillance. Through innovation, careful technique, and multidisciplinary collaboration, glaucoma surgery continues to evolve as a cornerstone of vision preservation within modern ophthalmology.
